Oral mucosal cell response to Candida albicans in transgenic mice expressing HIV-1.

ABSTRACT

Controlled studies on the immunopathogenesis of mucosal candidiasis in HIV infection have been hampered by the lack of a relevant animal model. We have previously reported that oral Candida infection in CD4C/HIV transgenic mice expressing gene products of HIV-1 in immune cells and developing an AIDS-like disease closely mimics oropharyngeal candidiasis in human HIV infection. The role of defective dendritic cells and CD4+ T cells in impaired induction of protective immunity and in the phenotype of chronic oral carriage of C. albicans can now be investigated under controlled conditions in these transgenic mice.
